An analytical tool based on the finite element methoi h~s been developed, using segments of s curved bar with 3 degrees of freedom at each end to s~,late a thin pipe, triangular, isoparametric elements with one curved boundary 3 midside nodes to simulate the soil, an interaction element with zero thickness to simulate interface behaviour. A computer program was written and used on some examples to investigate the influence of nonlinear soil properties, rel~bive stiffness of pipe and soil, inclusion of weak materials near the spring line, and construction ~rocedures. ~ The study does not consider time-dependent pro:erties, temporary loads or cracking c~ yielding of the pipe Avail: University Microfilms, 18 Bedford Row, London WCIR 4EJ, UK
